Cellulosic ethanol developer ZeaChem has been named one of the 2011 Global Cleantech 100 companies. The annual list is produced by Cleantech Group in collaboration with UK’s Guardian News, focusing on companies they believe are likely to make the most significant impact over the next 5-10 years.

“ZeaChem is building a portfolio of advanced biofuels and bio-based chemicals derived from cellulosic biomass,” said Jim Imbler, CEO of ZeaChem. “As our 250,000 gallon demonstration plant nears completion in Boardman, Ore. and we develop our first commercial scale biorefinery, we are honored to be named in the 2011 Global Cleantech 100.”

Another advanced biofuels company that made the list for the second year was LanzaTech, a New Zealand-based firm working on the conversion of a nonfood feed stocks into bioethanol. LanzaTech was also named “Company of the Year Asia Pacific” for 2011.

A number of solar companies also made the list, including SolarCity and eSolar of California.
